Unscramble the Blue Letters

It turns out that giant clams have a giant impact on coral reefs. These multitasking clams are reef builders, food factories, sertelhs for shrimps and crabs and water filters, all rlloed into one. In a nutshell, giant clams play a major contributing role as restdneis of their own reef home, and just having them around keeps the reef healthy. And because they can live up to 100 years old, giant clams make vital icraintods of coral reef health. So when giant clams start to disappear from coral reefs, their absence can serve as an alarm bell for stiiesncts to start paying ainottetn, smiailr to the canary in a coal mine. But giant calms are endangered. The largest clam in the world is fcnaig the threat of extinction, with more than 50 pneerct of the wild piltauopon severely depleted. And the ecological bitfeens of having giant clams on coral reefs are likely to continue only if populations are healthy, making their conservation paramount.

Original Text

It turns out that giant clams have a giant impact on coral reefs. These multitasking clams are reef builders, food factories, shelters for shrimps and crabs and water filters, all rolled into one. In a nutshell, giant clams play a major contributing role as residents of their own reef home, and just having them around keeps the reef healthy. And because they can live up to 100 years old, giant clams make vital indicators of coral reef health. So when giant clams start to disappear from coral reefs, their absence can serve as an alarm bell for scientists to start paying attention, similar to the canary in a coal mine. But giant clams are endangered. The largest clam in the world is facing the threat of extinction, with more than 50 percent of the wild population severely depleted. And the ecological benefits of having giant clams on coral reefs are likely to continue only if populations are healthy, making their conservation paramount.
